The UK mortgage and property market ended the past week with another reminder that buyers, sellers and homeowners are operating in a highly price-sensitive environment.
New Rightmove figures showed the largest August fall in average asking prices since 2018, while the average two-year fixed mortgage rate tracked by the property portal increased again. Separate housing-market data also pointed to cautious buyer demand, although the UK economy continued to show resilience during the second quarter of 2026. For mortgage borrowers, the picture remains mixed.
Property prices are coming under pressure in parts of the market, potentially strengthening the negotiating position of some buyers. At the same time, mortgage borrowing remains more expensive than it was earlier in the summer, and uncertainty around inflation and future Bank of England decisions continues to affect the outlook.
Here’s what happened in the UK mortgage and property market between 10th and 17th August 2026.
Quick Summary
- Rightmove reported a 2% monthly fall in average new asking prices, the largest August decline since 2018.
- The national average new asking price fell to £364,999.
- Asking prices were 1% lower than a year earlier.
- London recorded some of the weakest price performance in the country.
- Rightmove’s average two-year fixed mortgage rate increased to 5.09%, from 4.92% a month earlier.
- Housing market activity remains subdued, according to the latest RICS evidence.
- The UK economy grew by 0.4% in Q2 2026.
- Bank of England Chief Economist Huw Pill said the resilience of the economy strengthened the case for higher interest rates, highlighting the continuing uncertainty around borrowing costs.
Rightmove: Asking Prices Fall 2% In August
The biggest property-market development this week came from Rightmove. Average asking prices for newly listed homes fell by 2% over the four weeks to the 8th of August, equivalent to a reduction of around £7,360 and taking the national average new asking price to £364,999.
It was the largest August decline recorded by Rightmove since 2018 and was steeper than the average August fall of 1.3% seen over the previous decade. Average asking prices were also 1% lower than a year earlier, the largest annual decline since December 2023. It’s important to remember that Rightmove measures asking prices on newly marketed properties, rather than final completed sale prices.
Nevertheless, the figures provide a useful indication of seller sentiment and suggest that more vendors are responding to a market in which buyers remain highly conscious of affordability.
London Property Prices Face Greater Pressure
The national figure also hides significant regional differences. Rightmove reported that London experienced the sharpest annual decline, with asking prices around 3.1% lower than a year earlier. The capital also has particularly high levels of property available for sale, increasing competition between vendors.
Separate reporting on the new figures showed particularly pronounced falls in some prime London markets. In Kensington and Chelsea, for example, the average asking price of a newly listed home fell by more than £95,000 between the latest readings.
For London buyers, this doesn’t necessarily mean every property is suddenly significantly cheaper. But it does reinforce something we’re seeing increasingly reflected in the market: correct pricing matters. Where a property has been sitting unsold or the seller is highly motivated, buyers may have more room to negotiate than they did during a stronger seller’s market.
Buyers Have More Choice
Another important part of the Rightmove figures is the amount of property currently available. The number of homes available for sale is at its highest level for this time of year in around 16 years, creating greater competition between sellers. That matters because when buyers have more choice, sellers have less ability to rely on scarcity to achieve an ambitious asking price. For someone who is financially prepared and has already established their mortgage affordability, that can potentially create opportunities.
This is particularly relevant for buyers who:
- Have a mortgage Agreement in Principle
- Understand their maximum borrowing capacity
- Have their deposit readily available
- Are willing to negotiate
- Are purchasing from a motivated seller
In a slower property market, being mortgage-ready can strengthen your position as a buyer.
Mortgage Rates Have Moved Higher
The property-price story needs to be considered alongside mortgage costs. Rightmove’s latest data showed that the average two-year fixed mortgage rate increased to 5.09%, compared with 4.92% a month earlier.
This follows the volatility seen in fixed-rate mortgage pricing over recent months as lenders have responded to movements in wholesale funding costs and wider geopolitical uncertainty.
It highlights an important point for borrowers:
Falling property prices don’t automatically mean housing affordability is improving by the same amount. If the mortgage required to purchase the property becomes more expensive, some of the benefit of negotiating a lower price can be offset by higher monthly mortgage payments. That’s why buyers should consider property price and mortgage cost together, rather than looking at either in isolation.
Why Fixed Mortgage Rates Can Change Without A Base Rate Change
Fixed mortgage rates aren’t determined solely by the Bank of England Base Rate. Lenders also consider wholesale funding costs and financial-market expectations about where interest rates and inflation are likely to move in the future. This means mortgage rates can increase or decrease even when the Bank of England has not changed the official Base Rate.
Recent geopolitical uncertainty and concerns around energy costs and inflation have contributed to volatility in borrowing markets, which has fed through into mortgage pricing. For borrowers, this is why waiting for the next Bank of England meeting doesn’t necessarily tell you what will happen to fixed mortgage rates in the meantime.
UK Economy Grows By 0.4%
There was also important economic news this week. Figures released on 13th August showed that the UK economy grew by 0.4% during the second quarter of 2026, following growth of 0.6% during the first quarter.
Information and communications were among the areas supporting growth, with technology and AI-related activity making a notable contribution. On the surface, stronger economic growth is positive. However, the relationship with mortgages is more complicated.
If the economy remains resilient while inflationary pressures persist, the Bank of England may have less reason to reduce interest rates quickly. That means strong economic data can sometimes create upward pressure on interest-rate expectations, even when the wider economy appears healthy.
Bank Of England’s Huw Pill Highlights Rate Risk
That relationship became particularly relevant this week when Bank of England Chief Economist Huw Pill said the stronger UK growth figures supported the argument for higher interest rates. Pill has remained concerned about persistent inflation and argued that the resilience of the economy reduces the risk that tighter monetary policy would trigger a severe downturn. This does not mean that a Bank Rate increase is guaranteed. But it reinforces the uncertainty facing mortgage borrowers. Pill was one of three MPC members who voted to increase Bank Rate from 3.75% to 4% at the Bank’s latest meeting, while six members voted to keep rates unchanged.
Rather than assuming rates will inevitably fall later in the year, borrowers should recognise that Bank of England decisions will continue to depend heavily on incoming inflation, wage and economic data.
Housing Market Activity Remains Subdued
Separate housing-market evidence released during the week also pointed to relatively weak activity. Housing-market reporting published this week, drawing on the latest RICS survey evidence, also pointed to relatively weak activity. Buyer enquiries, agreed sales and house-price sentiment remained under pressure, reinforcing the picture of a cautious and price-sensitive market. This fits with the broader picture emerging from Rightmove.
There are buyers in the market, but they are generally more price-conscious and affordability-sensitive than during periods when mortgage costs were lower. For sellers, this means unrealistic pricing can make it considerably harder to attract interest. For buyers, however, a quieter market can create negotiating opportunities, particularly if they’re financially prepared and able to proceed.
Buyer Demand Shows Some Signs Of Improvement
Despite the weaker headline housing data, Rightmove did identify one encouraging sign.
Buyer demand increased by around 5% following the change of Prime Minister on 20th July, although demand remained approximately 10% below the level recorded a year earlier. This is an important distinction.
The market isn’t experiencing a broad collapse in activity. Instead, buyers appear to be operating more selectively. Properties that are priced appropriately and meet buyers’ requirements can still attract interest, while homes priced too aggressively may struggle.
What Does This Mean For First-Time Buyers?
For first-time buyers, the latest property-price figures could provide some encouragement. Greater seller competition and softer asking prices may improve negotiating opportunities in certain areas. However, mortgage affordability remains the bigger challenge for many borrowers.
Someone negotiating £10,000 or £20,000 from a property’s asking price still needs to qualify for the required mortgage and be comfortable with the monthly payments.
For first-time buyers, we’d therefore prioritise:
- Establishing realistic borrowing capacity
- Understanding the deposit required
- Securing an Agreement in Principle
- Comparing lender affordability
- Budgeting for mortgage payments at current rates
- Negotiating on the property once the finances are clear
What Does This Mean For Home Movers?
Home movers face a slightly different calculation. A softer market can create opportunities when purchasing the next property, but homeowners also need to consider the price they may achieve on their existing home. The important figure isn’t necessarily whether house prices nationally have fallen by 1% or 2%. It’s the relationship between:
The price you can achieve for your current property
and
The price you’re able to negotiate on your next one.
For someone moving to a substantially more expensive property, a softer market can sometimes work in their favour if the absolute discount on the property they’re buying is larger than the reduction on the property they’re selling.
What Does This Mean For Larger Mortgage Borrowers?
For professionals and higher earners requiring £500,000, £750,000, £1 million or larger mortgages, the current environment makes lender selection particularly important.
A small difference in mortgage rate matters more when the loan is large. But rate isn’t the only consideration.
Different lenders may also take very different approaches to:
- Bonuses
- Commission
- RSUs
- Partnership income
- Dividends
- Investment income
- Foreign currency earnings
- Future income
- Overall affordability
- Maximum income multiples
In a market where mortgage pricing is moving quickly, understanding both which lender is prepared to lend the amount required and what it will cost becomes particularly important.
Oportfolio Insight
This week highlights an interesting disconnect in the property market. Property asking prices are falling, but mortgage rates have moved higher. At first glance, falling property prices sound like straightforward good news for buyers. But affordability depends on more than the purchase price.
Consider someone negotiating £25,000 off a property but requiring a substantial mortgage. If the mortgage rate available to them has increased at the same time, the saving on the purchase price may not translate directly into the improvement in monthly affordability they expected. That’s why we believe buyers should avoid looking at house prices and mortgage rates as two separate conversations. They’re part of the same affordability calculation.
For professionals and higher earners in London and the South East, there’s another layer: the lender’s treatment of income. Two buyers could negotiate the same property to the same price and have the same deposit, but receive different borrowing outcomes depending on how their respective lenders assess salary, bonuses, commission or other income.
The property market determines the price you negotiate. The mortgage market determines how you finance it. Successful buyers need both sides of that equation to work.
What Borrowers Should Watch Next
Over the coming weeks, some of the most important factors for mortgage borrowers will be:
- UK inflation data
- Bank of England commentary
- Swap-rate movements
- Mortgage lender repricing
- Energy prices
- Buyer demand
- Autumn housing-market activity
- Further information ahead of the October Budget
The direction of mortgage rates is unlikely to be determined by any single one of these factors. Borrowers should therefore be cautious about trying to predict the exact bottom of the market.
Key Takeaways
- Rightmove reported a 2% fall in new asking prices in August, the biggest August drop since 2018.
- The average newly listed property price fell to £364,999.
- Asking prices were 1% lower year-on-year.
- London experienced greater downward pressure than the national average.
- The average two-year fixed mortgage rate tracked by Rightmove increased to 5.09%.
- Buyers have considerable property choice, strengthening competition between sellers.
- Housing-market activity remains subdued and price-sensitive.
- UK GDP grew by 0.4% in Q2 2026.
- Stronger economic growth and persistent inflation risks mean the future path of interest rates remains uncertain.
- Buyers should consider property price, mortgage affordability and lender criteria together.
In Summary
The UK mortgage market between 10th and 17th of August 2026 remained characterised by mixed signals. Property sellers are becoming more competitive, with Rightmove recording the largest August fall in asking prices since 2018. But mortgage costs have moved in the opposite direction, with the average two-year fixed rate tracked by Rightmove increasing from 4.92% to 5.09%.
At the same time, stronger UK economic growth has reduced the certainty that lower interest rates are just around the corner. Bank of England policymakers continue to focus closely on inflationary pressures and the resilience of the economy. For buyers, this creates both opportunities and challenges.
A more price-sensitive property market may create room to negotiate, but securing the right mortgage remains essential. Rather than trying to perfectly time either property prices or mortgage rates, borrowers are generally better served by understanding their deposit, borrowing capacity, lender options and monthly affordability before committing to a purchase.
